Detailed Description

Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

The Long Term Evolution (LTE) system R15 release introduced idle mode measurements to quickly establish Carrier Aggregation (CA).

The 3GPP protocol is under study for LTE _ NR _ DC _ CA _ enh WI, one of the targets being early measurement. The work item contains the following objectives (RP-190452):

early measurement reporting: early and fast reporting of measurement information availability of neighbor and serving cells to reduce delay in establishing multi-RAT dual connectivity (English: MR-DC) and/or CA

The present object is applicable to MR-DC, NR-NR-DC and CA. The target should consider measurements in idle, inactive and connected states.

The impact on the power consumption of the terminal equipment should be minimized.

When applicable, work with LTE rel-15euCA should be used.

For early measurements, 3GPP has currently agreed some consensus, including:

the NR early measurement may be configured in the NR RRC release message and the NR system information.

For the NR idle state, LTE rel-15euCA early measurement reporting solution after connection establishment is supported (i.e. through terminal information request and terminal information response messages).

For the NR inactive state, LTE rel-15euCA early measurement reporting solution after connection is resumed (i.e. through terminal information request and terminal information response messages) is supported.

For the NR inactive state, the mobile communication Network (NW) may request an early measurement report in the RRC connection resume message.

For the NR inactive state, the terminal device may send an early measurement report in the RRC recovery complete.

When the terminal device performs early measurement, in some cases, the early measurement result obtained by the early measurement does not help to quickly establish MR-DC and/or CA. For example, the terminal device moves faster, the early measurement result changes continuously, and the wireless environment changes when the connection is finally established. When the terminal device moves fast, the early measurement brings extra power consumption of the terminal device, and the reporting of the early measurement result brings air interface overhead.

Therefore, the embodiment of the disclosure provides a cell measurement control method, a cell measurement control device, a terminal and a storage medium. Receiving, by a terminal device, an early measurement configuration, the early measurement configuration being used to instruct the terminal device to perform early measurements; according to the mobile state of the terminal equipment, whether the terminal equipment carries out early measurement or not is controlled, the problem of larger power consumption caused by the fact that the terminal equipment monitors adjacent cells in the related technology is avoided, and unnecessary power consumption of the terminal equipment is reduced.

In step 201, an early measurement configuration is received, where the early measurement configuration is used to instruct a terminal device to perform early measurement.

Optionally, the terminal device receives an early measurement configuration sent by the access network device, where the early measurement configuration is used to instruct the terminal device to perform early measurement on the neighboring cell.

Optionally, the access network device sends a System Information (SI) or an RRC release signaling to the terminal device through a downlink channel, where the System Information or the RRC release signaling includes the early measurement configuration.

Step 202, controlling whether the terminal device performs early measurement according to the moving state of the terminal device.

Optionally, the terminal device determines its own moving state, and does not perform early measurement when the moving state of the terminal device is a fast moving state; when the moving state of the terminal device is not the fast moving state, early measurement is performed.

Optionally, the fast moving state is used to indicate that the moving speed of the terminal device is higher than a speed threshold. The speed threshold is either custom set by the terminal device, pre-configured by the access network device, or pre-defined by the communication protocol. This embodiment is not limited thereto.

Optionally, when the mobility state of the terminal device is not a fast mobility state, performing early measurement according to the early measurement configuration to obtain an early measurement result.

Illustratively, the early measurement results include signal quality of the cell on one or more frequencies.

Optionally, when the terminal device accesses the mobile communication network, it indicates to the access network device that there is an early measurement result available for the terminal device. When the terminal equipment receives the inquiry information sent by the access network equipment through the downlink signaling, the terminal equipment reports the early measurement result to the access network equipment. Correspondingly, the access network equipment configures MR-DC and/or CA according to the received early measurement result so as to provide high-speed data service for the terminal equipment through a plurality of carriers as soon as possible.

To sum up, the embodiment of the present disclosure receives, by a terminal device, an early measurement configuration, where the early measurement configuration is used to instruct the terminal device to perform early measurement; according to the mobile state of the terminal equipment, whether the terminal equipment carries out early measurement or not is controlled, the problem of larger power consumption caused by the fact that the terminal equipment monitors adjacent cells in the related technology is avoided, and unnecessary power consumption of the terminal equipment is reduced.

Referring to fig. 3, it shows a flowchart of a cell measurement control method according to another exemplary embodiment of the present disclosure, which is illustrated in the embodiment by using the method in the terminal device 140 shown in fig. 1. The method comprises the following steps.

In step 301, an early measurement configuration is received, where the early measurement configuration is used to instruct a terminal device to perform early measurement.

It should be noted that, for the process of receiving the early measurement configuration by the terminal device, reference may be made to relevant details in the foregoing embodiments, and details are not described herein again.

Step 302, obtaining a mobile parameter value of the terminal device, where the mobile parameter value is used to indicate a mobile state of the terminal device.

Optionally, the mobile parameter value of the terminal device includes: the cell reselection times of the terminal equipment in a first preset time period; and/or the speed of movement of the terminal device.

Optionally, the first preset time period is preconfigured for the access network device, or predefined for the communication protocol, or customized for the terminal device. This embodiment is not limited thereto.

Optionally, the terminal device obtains its own moving speed through the position sensor. The position sensor includes at least one of an acceleration sensor, a Global Positioning System (GPS) sensor, and a gyro sensor.

In step 303, when the value of the motion parameter is greater than the parameter threshold, no early measurement is performed.

Optionally, the terminal device determines whether the moving parameter value is greater than the parameter threshold, and if the moving parameter value is greater than the parameter threshold, step 303 is executed; if the moving parameter value is less than or equal to the parameter threshold value, go to step 304.

In one possible implementation manner, when the mobile parameter value includes a cell reselection number of the terminal device within a first preset time period, the parameter threshold is a number threshold. The terminal device judges whether the cell reselection times in the first preset time period is greater than a time threshold, and if the cell reselection times in the first preset time period is greater than the time threshold, the terminal device is used for indicating that the mobile state of the terminal device is a fast mobile state, and the terminal device does not perform early measurement.

In one illustrative example, the first predetermined time period is 1 minute and the number threshold is 8. The terminal device obtains that the cell reselection frequency in 1 minute is 10, and the terminal device judges that the cell reselection frequency "10" is greater than the frequency threshold "8" in 1 minute, namely when the mobile state of the terminal device is a fast mobile state, the terminal device does not perform early measurement.

It should be noted that, the specific values of the first preset time period and the number threshold are not limited in the embodiment of the present disclosure.

In another possible implementation, the movement parameter value includes a movement speed of the terminal device, and the parameter threshold is a speed threshold. The terminal equipment judges whether the moving speed is greater than a speed threshold value, and if the moving speed is greater than the speed threshold value, the terminal equipment is used for indicating that the moving state of the terminal equipment is a quick moving state, and the terminal equipment does not perform early measurement.

In one illustrative example, the speed threshold is 30 kilometers per hour. The terminal device obtains the self moving speed of 50 km/h through the GPS sensor, and judges that the self moving speed of 50 km/h is greater than the speed threshold of 30 km/h, namely when the moving state of the terminal device is a fast moving state, the terminal device does not carry out early measurement.

It should be noted that, the specific value of the speed threshold is not limited in the embodiment of the present disclosure.

In another possible implementation manner, the mobility parameter value includes a cell reselection number of the terminal device within a first preset time period and a mobility speed of the terminal device, and the parameter threshold includes a number threshold and a speed threshold. The terminal device judges whether the cell reselection times in a first preset time period are larger than a time threshold and judges whether the moving speed is larger than a speed threshold, if the cell reselection times in the first preset time period of the terminal device are larger than the time threshold and the moving speed is larger than the speed threshold, the terminal device is used for indicating that the moving state of the terminal device is a fast moving state, and the terminal device does not perform early measurement or suspend early measurement configuration.

Optionally, the parameter threshold includes: the access network equipment pre-configures a threshold value through broadcast signaling or dedicated signaling; alternatively, a communication protocol predefined threshold; or a self-defined threshold value of the terminal equipment. The specific value and setting mode of the parameter threshold are not limited in this embodiment.

Optionally, the access network device pre-configures the parameter threshold through signaling sent on a broadcast channel or a dedicated channel.

And 304, when the mobile parameter value is smaller than or equal to the parameter threshold value, performing early measurement according to the early measurement configuration to obtain an early measurement result.

Optionally, when the number of cell reselections of the terminal device in the first preset time period is less than or equal to the number threshold, and/or the moving speed of the terminal device is less than or equal to the speed threshold, the terminal device performs early measurement according to the early measurement configuration to obtain an early measurement result.

Optionally, the early measurement results comprise signal quality of the cell on one or more frequencies.

It should be noted that the RRC state of the terminal device includes one of an IDLE state "RRC _ IDLE", a connection state "RRC _ CONNECTED", and an INACTIVE state "RRC _ INACTIVE". The inactive state is a state different from the idle state and the connected state. The mobile communication network triggers the terminal device in the connection state to enter the non-activation state, and at this time, the terminal device and the mobile communication network both store the terminal device context in the RRC connection state before the non-activation state, including the configuration of the established signaling radio bearer, the configuration of the DRB, the measurement configuration, the security configuration and the like, and the context stored in the terminal device is slightly different from the context stored in the mobile communication network.

Optionally, the terminal device in the idle state performs early measurement according to the early measurement configuration, and obtains an early measurement result after a period of measurement.

In summary, in this embodiment, it is further determined, by the terminal device, whether the moving state of the terminal device is the fast moving state according to the cell reselection frequency of the terminal device in the first preset time period and/or the moving speed of the terminal device, so that the determined moving state of the terminal device is more accurate, and the accuracy of cell measurement control is further ensured.

Optionally, when the service to be processed of the terminal device needs to initiate an RRC connection request and desires to access the mobile communication network, the terminal device determines whether to report an early measurement result available to the terminal device to the access network device according to a service characteristic of the service to be processed.

The service characteristics of the service to be processed are used for indicating the service data volume of the service to be processed.

Optionally, the service characteristics of the service to be processed include an application type of the service to be processed. The application types include a first type application type and a second type application type, the first type application type is used for indicating an application program of which the data volume transmitted after starting is less than or equal to a traffic volume threshold, for example, the first type application type is used for indicating an instant messaging application program. The second type of application is used to indicate applications that have an amount of data transferred after startup that is greater than a traffic threshold. For example, the second type of application is used to indicate an online shopping application, an online audio playing application, an online video playing application, and the like.

When the application type of the service to be processed is the first type, the terminal equipment does not report an available early measurement result of the terminal equipment to the access network equipment; and when the application type of the service to be processed is the second type application type, the terminal equipment reports the available early measurement result of the terminal equipment to the access network equipment.

In a possible implementation manner, the terminal device is in an idle state or an inactive state, and the service characteristics of the service to be processed include a service data volume to be sent corresponding to the service to be processed. The above step 304 further includes the following steps, as shown in fig. 4:

step 401, in the process of RRC connection establishment or RRC connection recovery, when the traffic data volume to be sent exceeds the traffic volume threshold, reporting an early measurement result available to the terminal device to the access network device.

In a possible implementation manner, in the RRC connection recovery process, when the traffic data volume to be sent exceeds a traffic volume threshold, if the terminal device receives query information sent by the access network device through downlink signaling, the terminal device reports an early measurement result to the access network device. Wherein, the query information is information for querying an early measurement result.

Optionally, the traffic data volume to be sent is determined by the terminal device according to the history information. Illustratively, the terminal device records target data amounts corresponding to a plurality of applications of the terminal device. And when RRC connection establishment or RRC connection recovery is required, determining the target data volume corresponding to the application program running in the foreground as the service data volume to be sent. The target data volume is the data volume transmitted after the application program is started last time or the data volume transmitted after the application program is started every time in a second preset time period.

Optionally, the traffic threshold is preconfigured by the access network device through broadcast signaling or dedicated signaling, or predefined by the communication protocol, or is a threshold customized by the terminal device. This embodiment is not limited thereto.

The downlink signaling is used for indicating the terminal equipment to report the early measurement result to the access network equipment. Correspondingly, after receiving the query information, the terminal device reports the early measurement result to the access network device through the uplink channel.

The access network equipment receives an early measurement result reported by the terminal equipment through an uplink channel, and configures MR-DC and/or CA according to the received early measurement result.

In another possible implementation manner, in the RRC connection establishment or RRC connection recovery process, when the traffic data volume to be sent exceeds the traffic volume threshold, the terminal device indicates to the access network device that there is an early measurement result available for the terminal device. When the terminal equipment receives the inquiry information sent by the access network equipment through the downlink signaling, the terminal equipment reports the early measurement result to the access network equipment.

Optionally, when the traffic data volume to be sent does not exceed the traffic volume threshold, it does not indicate to the access network device that the terminal device has an available early measurement result.

Optionally, after receiving the query information, the terminal device reports the early measurement result to the access network device through an uplink channel. Correspondingly, the access network equipment receives the early measurement result reported by the terminal equipment through the uplink channel, and configures MR-DC and/or CA according to the received early measurement result.

In an illustrative example, when a terminal device in an idle state performs early measurements according to an early measurement configuration, the terminal device may obtain early measurement results on one or more frequencies after a period of measurement. At this time, the terminal device initiates an RRC connection request due to a new service requirement, and wants to access a network, and the terminal device can determine the size of the service data volume of the service in advance according to the service characteristics of the new service, such as the application type to which the new service belongs, whether the application is an instant messaging application, an online shopping application, or an online video application, and if the application is an instant messaging application, the corresponding service data volume is usually small; the method comprises the steps that the service data volume corresponding to an online shopping application, an online audio playing application and an online video playing application is large, the data volume corresponding to other downloading services is also large, a service volume threshold value can be preset by an access network device through system information, the terminal device does not report an available early measurement result to the access network device when judging whether the service data volume of a new service exceeds the service volume threshold value or not, and the reporting of the early measurement result does not consume precious wireless resources and wastes the power consumption of the terminal device. The configuration signaling of carrier aggregation/dual connectivity requires a large number of bits, and usually requires several kilobytes or more. The terminal equipment reports the available early measurement result to the access network equipment only when judging that the service data volume of the new service exceeds the service volume threshold, and at the moment, the access network equipment can rapidly configure the MR-DC and/or the CA so as to provide high-speed data service for the terminal equipment through a plurality of carriers as soon as possible.

In summary, in the RRC connection establishment or RRC connection recovery process, when the amount of the service data to be sent exceeds the traffic threshold, the embodiment also reports the early measurement result available to the terminal device to the access network device, so as to avoid extra overhead caused by reporting the early measurement result when the amount of the service data to be sent is small in the related art, and reduce unnecessary power consumption of the terminal device and air interface overhead.

In another possible implementation manner, before or when the terminal device enters the inactive state, the terminal device receives a pre-configured target Data Radio Bearer (DRB) that needs to report an early measurement result. And the terminal equipment is in an inactive state, and performs early measurement according to the early measurement configuration to obtain an early measurement result. And when the service to be processed exists in the terminal equipment, the RRC connection is restored through the restoration process. The number of target data radio bearers may be one or more.

Optionally, before the terminal device enters the inactive state, the access network device sends an RRC signaling to the terminal device, where the RRC signaling carries the configured target DRB. Correspondingly, the terminal equipment receives the RRC signaling.

Optionally, when the terminal device is in an inactive state, after performing early measurement according to the early measurement configuration to obtain an early measurement result, that is, after step 304, the method further includes the following steps, as shown in fig. 5:

step 501, in the RRC connection recovery process, when there is data to be sent on the target DRB, reporting an early measurement result available to the terminal device to the access network device.

In a possible implementation manner, in the RRC connection recovery process, when there is data to be sent on the target DRB, that is, when the terminal device is to carry uplink data through the target DRB, if the terminal device receives query information sent by the access network device through downlink signaling, the terminal device reports an early measurement result to the access network device. Wherein, the query information is information for querying an early measurement result.

Optionally, when data needs to be sent and the traffic data volume to be sent exceeds a traffic volume threshold, if the terminal device receives query information sent by the access network device through downlink signaling, the terminal device reports an early measurement result to the access network device.

It should be noted that, the process of the terminal device determining whether the traffic data volume to be sent exceeds the traffic volume threshold value may refer to the above related description, and is not described herein again.

Optionally, the terminal device reports the early measurement result to the access network device through an uplink channel. Correspondingly, the access network equipment configures MR-DC and/or CA according to the received early measurement result.

In another possible implementation, in the RRC connection recovery process, when there is data to send on the target DRB, the terminal device is indicated to the access network device that there is an early measurement result available. When the terminal equipment receives the inquiry information sent by the access network equipment through the downlink signaling, the terminal equipment reports the early measurement result to the access network equipment.

Optionally, in the RRC connection recovery process, when data exists on the target DRB and needs to be sent and the traffic data volume to be sent exceeds the traffic volume threshold, the access network device is indicated that the terminal device has an available early measurement result.

Optionally, when the DRB corresponding to the data to be sent is the target DRB, indicating to the access network device that the terminal device has an available early measurement result; and when the DRB corresponding to the data to be sent is not the target DRB, not indicating the terminal equipment to have available early measurement results to the access network equipment.

In summary, in this embodiment, the terminal device receives the pre-configured target DRB that needs to report the early measurement result in advance, and reports the available early measurement result of the terminal device to the access network device when there is data to be sent on the target DRB in the RRC connection recovery process, so that unnecessary power consumption and air interface overhead of the terminal device are reduced, and the performance of the terminal device is further improved.

Referring to fig. 6, it shows a flowchart of a cell measurement control method according to another exemplary embodiment of the present disclosure, which is illustrated in the embodiment by using the method in the terminal device 140 shown in fig. 1. The method comprises the following steps.

Step 601, the terminal device receives a pre-configured target DRB that needs to report an early measurement result.

Optionally, before the terminal device enters the inactive state or when the terminal device enters the inactive state, the terminal device receives a pre-configured target DRB that requires reporting of an early measurement result. And the terminal equipment is in an inactive state, and performs early measurement according to the early measurement configuration to obtain an early measurement result. And when the service to be processed exists in the terminal equipment, the RRC connection is restored through the restoration process.

Optionally, the terminal device receives a pre-configured target DRB that needs to report an early measurement result, which may refer to the relevant details in the foregoing embodiment and is not described herein again.

Step 602, in the RRC connection recovery process, when there is data to be sent on the target DRB, the terminal device reports an early measurement result available to the terminal device through an uplink channel.

Optionally, in the RRC connection recovery process, when the DRB corresponding to the data to be sent is the target DRB, reporting an available early measurement result of the terminal device through an uplink channel; and when the DRB corresponding to the data to be sent is not the target DRB, not reporting the available early measurement result of the terminal equipment.

Optionally, in the RRC connection recovery process, when data needs to be sent and the amount of service data to be sent exceeds the service amount threshold, an available early measurement result of the terminal device is reported through an uplink channel.

In an illustrative example, the terminal device may perform early measurements according to an early measurement configuration configured in a system message or according to an early measurement configuration configured in an RRC connection release while in an inactive state. When the terminal equipment has service requirements, the RRC connection can be restored through a restoration process, data communication can be restored quickly in the restoration process, and the quantity of RRC signaling is reduced. Because the service data volumes of different DRBs may be greatly different, the service data volumes corresponding to some DRBs are very small, and the service data volumes corresponding to some DRBs are very large. When the DRB with small service data volume has data to be sent, the terminal equipment implements a recovery process to recover the uplink and downlink paths of the DRB, and at the moment, if the terminal equipment reports an early measurement result, the data transmission of the DRB is not helped except for consuming precious wireless resources, because the MR-DC and/or CA does not need to be configured for the transmission of small data volume. At this time, the method for determining the traffic data volume may be reused, for example, the terminal device determines whether to report an early measurement result available to the terminal device to the access network device in the recovery process based on the traffic threshold; and/or configuring, by the base station, a target DRB that needs to report an early measurement result through RRC signaling before the terminal device does not enter the active state.
